At this point it’s simply a proposal. And a proposal that would not only require a significant upzoning of the parcel (currently 220 feet), but an upzoning of the upzoning that’s already in the works (350 feet). But if Fritzi Realty gets its way, a 550-foot residential tower designed by SOM will rise up at 41 Tehama.

The 54-story glass tower, designed by Skidmore Owings & Merrill, would be one of the tallest residential buildings in the new Transbay District, with 350 housing units soaring up from a long, skinny 22,000-square-foot parcel, according to an application for environmental impact review filed with the city.

We’re not holding our breadth, but we will cross our fingers (both for the development and that a rendering manages to land in our inbox).
